tpt-rust7

The Pragmatic Workspace: Time, Merge, Context, Effects, Schema.

tpt-rust7 is a multi-crate workspace from TPT Solutions designed for immediate, frictionless adoption (cargo add). It addresses the most common daily frustrations in Rust development — flaky async tests, distributed state synchronization, telemetry boilerplate, complex state machines, and serialization overhead — without requiring developers to learn formal verification.

Each crate is completely independent: they share no internal dependencies, so you can adopt tpt-time without pulling in the telemetry or effect machinery. They rely on standard Rust traits and minimal proc-macros to keep compile times low.

Crates

Crate	Primitive	What it solves
tpt-time	Deterministic Virtual Time	Drop-in replacement for tokio::time / std::time. Zero-overhead OS clock in production; injectable VirtualClock in tests.
tpt-merge	Commutative Merge Traits	Core Merge trait (commutative, associative, idempotent) with LWWRegister, ORSet, GCounter CRDTs.
tpt-context	Lifetime-Bound Telemetry	Implicitly threads tracing/metrics context across async boundaries via scoped thread-locals + lifetime-bound tokens.
tpt-effects	Typed Effects	Proc-macro state-machine generator for orthogonal effects via #[effects(state: T, reader: T, error: E)].
tpt-schema	Zero-Copy Evolution	Self-describing tag/length/value wire format with a versioned header; compiler-checked forward/backward compatibility for zero-alloc reads.
